Parameter Range Default Usage
Parameter 1-45
q-axis Induc-
tance Sat.
(LqSat) 0.000–1000.000 mH Size related This parameter corresponds to the inductance saturation of
Lq. Ideally, this parameter has the same value as
parameter
1-38 q-axis Inductance (Lq) . However, if the motor supplier
provides an induction curve, enter the induction value, which
is 200% of the nominal current.
Parameter 1-46
Position Detec-
tion Gain 20–200% 100% Adjusts the height of the test pulse during position detection
at start.
Parameter 1-48
Current at Min
Inductance for
d-axis 20–200% 100% Enter the inductance saturation point.
Parameter 1-49
Current at Min
Inductance for
q-axis 20–200% 100% This parameter specifies the saturation curve of the d- and q-
inductance values. From 20–100% of this parameter, the in-
ductances are linearly approximated due to
parameter 1-37 d-
axis Inductance (Ld) , parameter 1-38 q-axis Inductance (Lq) , pa-
rameter 1-44 d-axis Inductance Sat. (LdSat) , and parameter 1-45
q-axis Inductance Sat. (LqSat) .
Parameter 1-70
PM Start Mode [0] Rotor Detection
[1] Parking
[0] Rotor De-
tection Select the PM motor start mode.
Parameter 1-73
Flying Start [0] Disabled
[1] Enabled
[0] Disabled Select [1] Enabled to enable the drive to catch a spinning mo-
tor.
Parameter 3-41
Ramp 1 Ramp
Up Time 0.05–3600.0 s Size related Ramp-up time from 0 to rated parameter 1-23 Motor Frequen-
cy .
Parameter 3-42
Ramp 1 Ramp
Down Time 0.05–3600.0 s Size related Ramp-down time from rated parameter 1-23 Motor Frequency
to 0.
Parameter 4-12
Motor Speed
Low Limit [Hz] 0.0–400.0 Hz 0.0 Hz Enter the minimum limit for low speed.
Parameter 4-14
Motor Speed
High Limit [Hz] 0.0–400.0 Hz 100.0 Hz Enter the maximum limit for high speed.
Parameter 4-19
Max Output
Frequency 0.0–400.0 Hz 100.0 Hz Enter the maximum output frequency value. If parameter 4-19
Max Output Frequency is set lower than parameter 4-14 Motor
Speed High Limit [Hz] , parameter 4-14 Motor Speed High Limit
[Hz] is set equal to parameter 4-19 Max Output Frequency auto-
matically.
